Mouth asymmetry during speech of epileptic patients who have undergone carotid amytal testing.

Asymmetry in the opening of the two sides of the mouth during speech has been suggested as an observable correlate of lateralization of cerebral speech motor control. For 24 epileptic patients who suffered speech disturbance only during left hemisphere carotid amytal anesthetization, 22 showed the expected greater opening of the right side of the mouth during a repetition task. However, all four of the patients who suffered speech disturbance following only right hemisphere anesthetization, and 8 of the 11 "bilateral speech" patients, also showed greater opening of the right side of the mouth. The speech dominant patients may, however, have genetic left speech dominance but a pathology-forced shift of some components of language to the right hemisphere. Basic mouth asymmetry, as measured here, may primarily reflect lateralization of a component of the motor/speech/language control system that may not be shifted by pathology in epileptic patients sustaining early brain insult. Relative change in mouth asymmetry as the speech task becomes more demanding may, however, be a more sensitive indicator or cerebral asymmetries for language in pathological cases.

Cerebral organization of affect suggested by temporal lobe seizures.

A right-handed woman with independent left- and right-sided temporal lobe discharges was studied by continuous EEG and videotape monitoring for 3 weeks. Changes in affect were noted in the immediate and extended postictal periods and varied with the side of discharge. After a left-sided discharge, she became globally aphasic and depressed. Right-sided discharges evoked laughing and postictal hypomania. These manifestations were attributed to contralateral hemispheric disinhibition after ipsilateral seizure inactivation. This case provides evidence that the speech-dominant hemisphere subserves positive feelings and the nondominant hemisphere negative ones.

Lateralization in attainment and maintenance of neonatal head posture: further external validation.

Consistencies in lateral head turning of 50 healthy, term neonates were examined to determine relations between attainment and maintenance of lateral head position. The majority showed lateral consistencies, typically rightward, in initial head turn from midline per trial, in direction of the majority of all head turns from midline per trial and in direction turned for the majority of time per trial. Head position prior to testing was related to the three indices. The results of work to date, including the current study, have proven very consistent in nature, yielding the most reliable measure of an element of lateralized behavior in the neonate.

Long-term follow-up after cerebral hemispherectomy: neurophysiologic, radiologic, and psychological findings.

Eight patients were studied 3 to 16 years (mean, 10 years) after cerebral hemispherectomy. Seven have infantile hemiplegia, and one had Sturge-Weber disease. Preoperative assessment included EEG responses to intracarotid drug injections. Postoperative complications occurred in seven patients. The operation was followed by a marked reduction in seizure frequency and improvement in behavior, with little change in intellect or hemiplegia. Neuropsychological assessment performed in four patients showed that they were not aphasic, but nonverbal spatial abilities were poor. CT showed marked shift of the remaining hemisphere in five of six patients scanned.

[New problems and results in behavior therapy].

What is presently observed is not only a rapid increase in the number of publications, but also a major change in the theoretical principles of behavior therapy. The former onesidedness of a form of behavior therapy theoretically substantiated by classical conditioning only may be regarded as having been completely overcome. For example, this is evident from new approaches to behavior diagnosis as an essential prerequisite of differentiated therapy planning. Recent concepts of the theoretical substantiation of the effectiveness of behavior therapy lead to an increasing consideration of both cognitive and motivational aspects and also take into account the complexity of the patient's social relations. This, in turn, results in the availability of a wide range of indication-specific methods of behavior therapy.
